Crate static_id

StaticId

This library provides an extremely memory-efficient implementation of StaticId for handling interned identifiers with optimal performance.

Features

• StaticId: A highly optimized, interned identifier type combining a code and a venue.
• Exceptional memory efficiency: Each StaticId is represented by a single 64-bit pointer.
• Ultra-fast comparisons: Equality checks and hashing operations only compare 8 bytes, regardless of the actual string length.
• Lazy evaluation: The actual string data is only accessed during serialization.

Limitations

• The code component of a StaticId cannot exceed 32 bytes.
• The venue component of a StaticId cannot exceed 16 bytes.

Usage

use static_id::StaticId;

let id = StaticId::from_str("AAPL", "NASDAQ");
assert_eq!(id.get_id().code.as_str(), "AAPL");
assert_eq!(id.get_id().venue.as_str(), "NASDAQ");
 
assert_eq!(id.code_str(), "AAPL");
assert_eq!(id.venue_str(), "NASDAQ");

// Fast equality check (compares only 8 bytes)
let id2 = StaticId::from_str("AAPL", "NASDAQ");
assert_eq!(id, id2);
println!("ID: {}", id); // => AAPL@NASDAQ
